Vertigo?

I think I mentioned the other day that I climbed up the tower of the Palazzo Pubblico in Siena, which I believe is either the tallest or second-tallest secular structure in Italy, and it's 505 steps to get to the top. This is a shot of the Campo from either the very top or a look-out point just a little ways from the very top--I can't remember which, but I think it's the latter. That's a fountain down there (and not a terribly small one), and those are full-size human beings, not some specks on the lens of the camera.
